ATU-100 Automatic Antenna Tuner Kit 1.8-50MHz 100W w/ 0.96-Inch OLED Display Unassembled
ATU-100 Automatic Antenna Tuner Board Assembled 1.8-50MHz 100W 0.96" OLED Upgraded Hardware 3.2
Description:
This assembled antenna tuner ATU-100 is an automatic tuning antenna. When installing and using it, please try to use a short coaxial cable to connect the short wave machine to the in end of the antenna; use the out port to connect your antenna. When the ATU-100 detects that the tuned transmit power is reached and the standing wave value is greater than 1.3, the tuning can be started, and after the tuning is completed (within the ability of ATU-100, if your antenna is not well matched, it will not be able to be reduced below 1.3, please adjust the antenna), you can perform high-power communication test. The finished board comes with a 128*64 OLED display screen, which takes into account power saving and display font coordination; please pay attention to the consistency of the data cable (dat clk) when installing the screen.
